It’s the political season, and I want to cut Sarah Palin some slack. She and her family have endured disgusting, unjust verbal abuse over the years, and I like her, personally.

But some things cannot be overlooked. I would not be discussing her son’s arrest this week except that, in the highest-profile way, at a Tulsa rally, she did something grotesque and disturbing: She blamed President Obama for the fact that her 26-year-old son beat up his girlfriend this week.

Allegedly, I must say, since he hasn’t yet been convicted. But Palin did not claim that her son was innocent; she instead said that, because he served in Iraq, post-traumatic stress disorder was responsible for his behavior: “I can talk personally about this. I guess it’s kind of the elephant in the room — because my own family, going through what we’re going through today with my son, a combat vet having served in a Stryker brigade fighting for you all, America, in the war zone. But my son, like so many others, they come back a bit different. They come back hardened,” Palin said.
